摘要：随着现代化生活的不断进步，交通工具的发展显得格外重要，尤其是火车这种运输量大，运输成本低，效率高的交通工具的发展。在科学技术的支撑下，火车的发展日新月异，尤其是在当代生活中，高速列车已然成为人们出行必不可少代步工具。但是随着火车的发展，对速度的追求不断提升，也产生了许多需要解决的问题，其中比较引人注意的就是随着列车速度的提升所带来的振动导致的运行不平稳、不安全以及乘坐舒适性等一系列问题。20497
为了解决这些问题，本文主要研究了如何优化高速列车减震系统，主要是对高速列车半主动减震系统中的重要组成部分可调阻尼减震器的研究以及对列车悬挂结构的刚度等力学特性分析与校核，通过了解减震原理采用相应的解决措施来使高速列车运行达到最合理、平稳、安全、舒适的运行状态。对可调阻尼减震器主要分析对比阻尼减震器的两种不同循环回路方式，选取合适的循环回路方式以及对阻尼减震器的结构设计。

Abstract：With the continuous advancement of modern life, the development of transport is
particularly important, especially in the development of the high-speed train, with transport
volume,low transportation cost, high efficiency。In support of science and technology, the
rapid development of the train, especially in contemporary life, high-speed train has become an
essential means of transport for people to travel. But with the development of the train, on the
speed of the pursuit of continuous improvement, it generated a lot of problems to be solved, one
of the more notable problem is caused by the train speed caused unstable, unsafe and
uncomfortable and other issues.
To solve these problems, this paper studies how to optimize the high-speed train damping
system, mainly study adjustable damping shock absorbers ,an important part of the high-speed
trains semi-active damping system and analysis and checking the mechanical properties of train
suspension stiffness of the structure . By understanding the principles of damping and use
corresponding measures to make high-speed trains to run to achieve the most rational, stable,
safe and comfortable operation. Adjustable damping shock absorbers for the main analysis
comparing two different ways circulation loop damping shock absorbers, select the appropriate
circulation loop mode and structural design of the shock absorber damping.
